Window Cleaning Process

Here's Exactly What We Do

We start with a thorough assessment of your windows, checking for any issues that need special attention like hard water stains or paint spots. No surprises, no hidden problems discovered halfway through.

Next comes the actual cleaning using professional-grade squeegees, eco-friendly solutions, and techniques designed for streak-free results. We clean both sides of the glass, plus frames and sills that collect dirt and debris.

The final step is a quality check to make sure every window meets our standards. If we missed something, we fix it before we leave. You shouldn’t have to point out spots we missed or deal with streaks after we’re gone.

Residential Window Cleaning Services

What's Included In Every Service

Every window cleaning service includes both interior and exterior glass cleaning, frame wiping, and sill cleaning. We bring our own water, equipment, and eco-friendly cleaning solutions.

For Germantown homes, we’re familiar with the common window types and challenges in the area. Whether you’re dealing with hard water spots from sprinkler systems or pollen buildup during spring months, we’ve seen it before and know how to handle it.

We also offer flexible scheduling because we understand your time is valuable. Regular maintenance schedules keep your windows consistently clean without you having to remember to call every few months.

How often should I have my windows professionally cleaned?

Most Germantown homeowners benefit from professional window cleaning every 3-4 months, though this depends on your specific situation. Homes near busy roads or with sprinkler systems that hit windows might need more frequent cleaning. Homes in quieter areas with good drainage can often go 6 months between cleanings. We’ll give you an honest assessment based on your property’s specific needs, not a one-size-fits-all recommendation.
Cloudy days are actually ideal for window cleaning. Direct sunlight causes cleaning solutions to dry too quickly, which can lead to streaking. Overcast conditions give us the perfect working environment for streak-free results. We’ll reschedule if there’s active rain, but light clouds or overcast skies are perfect weather for professional window cleaning.
We handle screen cleaning as an add-on service since dirty screens defeat the purpose of clean windows. Screens are carefully removed, cleaned with appropriate solutions, and reinstalled properly. For storm windows, we clean both the storm window and the window behind it if you’re having them removed seasonally. Just let us know what you need when scheduling.
Most hard water stains and paint spots can be removed with the right techniques and tools. We use specialized scrapers and solutions designed for these issues. However, some stains that have been left untreated for years may have permanently etched the glass. We’ll assess the situation and let you know what’s possible before starting any restoration work.
Yes, we use eco-friendly cleaning solutions that are safe for your landscaping, pets, and family. Our solutions are biodegradable and won’t harm plants or grass around your home’s foundation. We’re also careful about runoff and take steps to protect sensitive plants during the cleaning process. Your family’s safety and your property’s landscaping are both important to us.
If you’re not completely satisfied with our window cleaning service, we’ll return to address any issues at no additional charge. This rarely happens because we do a quality check before leaving, but we stand behind our work. We want you to be happy with the results and confident in recommending us to your neighbors. Your satisfaction is how we build our reputation in the Germantown community.
